Application filed February 7. 1812. Serial No. 676,087

To all whom it may concern Be it known that I, Moiuus lh s1mw.\ssun. residing in the city, county. and State of New York. have invented certain new and useful Improvements in the .\rt of Manufacturing Leggings. of which the following is a specification.

This invention relates to a certain-new and useful art of manufacturing garments of leather. cloth or like material. as for in more or less broad than those stated above.

will be in part obvious and in part specifically referred to in the course of the following description of the various steps included in the process which constitutes the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings \vhich'a re to be taken as a part of this specification, and to which reference is to be had for a better understanding of the invention; Figure 1 is a plan view of a blank such as may be operated upon in the course of the manufacture according to one embodiment of my process; Fig. is a plan view of the .blank shown in Fig. l as it appears in a later stage of the process; Fig. 1-) is an elevation showing such a blank as shown in Fig. .2, in place upon a certain torn'iing apparatus which may be used in connection with the practice ot my process: Fig. 4 is a view similar to Fig. I), but showing the blank properly shaped by the manipulation of the forming apparatus; Fig. 5 is a top plan view of the expanding l'ormer; Fig. (3 is a plan view of a blank such as may be operated upon in a slightly ditl'erent cn'ibodimcnt of my process from that shown in the preceding figures: Fig. 7 is a plan view of the blank shown in Fig. 6 as it appears in a later stage of the process; Fiq'. 8 is a view in elevation showing such a blank as shown in Fig. 7 in place upon the forming apparatus; F ig. 9 is a view similar to Fig. 8,but showing the blank properly shaped by the manipulation of the forming apparatus; Fig. 10 is a sectional view taken substantially on the line l0--10 of Fig. 5) showing the manner in wvhich a portion of the blank is shaped by the forming apparatus; Fig. 11 is a sectional view taken on the line ll-- -l l of Fig. 9), and Fig.

12 is a view in perspective showing a coin pleted legging which has been constructed in accordance with the embodiment of my process shown in the last six preceding fig ures of the drawings.

I will proceed to describe one embodiment of my invention as it applied to the manufacture o-t leggings or the like, which articles. mrticularly when made of leather. should preferabtvbe of a single piece of material adapted to encircle the leg, with its longitudinal edges meeting at the front to permit of easy adjustment and fastening. and with a bulged portion at the back which conforms to the shape of the leg. For obvious reasons the edge portions of the article should be substantially straight; and it is one of the charm-teristics of my new art that I am enabled to cut the. blank at its e'dg s in such a manner as will predetermine the bulge at the back 'of the finished article, while the finished. article will nevertheless have straight edges. and there will have been no cutting away o't material after the first cutting of the blank. Accordingly, the first step in the practice of the first embodiment of my invention is the provision of a suit able blank of leather or the like material.

which may be cut as shown in Fig. l with top and bottom edges l and 2, preferably parallel, and with similar outwardly curved or otherwise non-rectilinear side edges 3 and 4. This blank is next soaked in water or other liquid to make it more pliable. 'lhere after the blank is folded upon a mcdianline. with the edges 3 and 4 superposed one over the other. and these edges are secured together as by a line of stitching. Obviously. instead of cutting the edges in the manner described I may make them straight in the first instance and give to the line of stitching the desired curvature. In either case the line of stitching defines the edges of the tin.

ishcd legging. The blank formed as described, and as shown for example in Fig. 2. constitutes, when it is opened up, a tube. having a longitudinally straight side 5 and a side 6 opposite to the side 5, longitudinally curved or otherwise non-reetili: zar in accordancewith the line of the stitching. In the illustrative operation which I am describing, and which leads to the production. of a legging having a bulge at the back as shown in Fig. 4., the side 6 will be curved substantially as shown in Fig. 2, so that the tube will have a greater cross-sectional area at one end than at the other. This tube is now manipulated, preferably by means of the application of pressure interiorly of the tube against the material thereof, until the curved side 6 has become straight, and the straight. side 5 has become curved to correspond with the original curve of the side 5. As an example of one way of doing this, I may place the tubular blank shown in Fig. 2 upon an expanding former shown in Figs. 3 and 4, which expanding formermay comprise relative-ly movable sections 7 and 8,

the section 7 having. an outwardly longitudinally straight side 9, and the section 8 having an outwardly longitudinally convexed surface 10, said surfaces 9 and 10 being on opposite sides of the expanding former as shown. Preferably the blank heretofore described has been out so that thezsmallest cross sectional area thereof is substantially equal to the greatest width of the expanding former when the latter is contracted. The tube, shaped as previously described and with its side 6 longitudinally bulgedfin substantially the same degree as is the surface 10 of the expanding, former, is placed upon the latter in the manner shown in Fig. 3, wtih the convexed or bulged part 6 of the tube overlying the longitudinally straight part 9 of the expanding former, and the straight part 5 of the tube overlying the convexed part 10 of the expanding former. The two sections of the expanding former are now caused to separate; in the apparatus described the section 7 moves relatively to section 8 through the intermediary of shafts 11 and 12 secured in,tho ends of the section 8 and threaded into the ends of section 7, said shafts having parallel movement by means of the connecting shaft 14 interposed between said shafts 11 and 12 and having miter gears at its ends engaging with corresponding gears on the shafts 1'1 and 12. In the illustrative showing, shaft 12 is the driving shaft and is operated by means of a crank handle 15 or a pulley 16. In any event, the sections '7 and 8 are aused to separate, and in separating the tube upon the expanding former is gradually distorlod fromits original form until it as sumcs thc form shown in Fig. l, thc erstwhile convcxcd portion (3 of thc tube bcconr ing :1 longitudinally v traight portion, as shown in Fig. 4, and thc part 5 of thc tubc assuming a longitudinally bulged or con- \excd form, as shown in Fig. l, in corrcspondencc with the original bulge or con i'cxity of side the tube in other words conforms to thc supcrlicial configuration of thc cxpanding l'orlncr, but without sul'ijcciing pne part of the tube to any greater degree of stretching than that to which another part is subjected, Since the blank was originally provided with a curved side 6 made in correspondence with the bulged surface lO of the expanding"former, it follows that when what was the convexed or bulged surface 6 becomes longitudinally straight, as shown in Fig. 2, the forming operation may be taken to be completed, and further expansion of 1 the expanding former stopped. The tube is now split along its longitudinally straight side, which will be the front of the legging, and subsequently finished up into a complete legging, such as is familiar.

The embodiment of my process shown in F (S to 12 inclusive, relates more especially to the manufacture of leggings out of cloth. In this embodiment of my invention blank 17 is provided, which blank may be cut oblong, as shown, and then folded along the median line '18, and the material then stitched along the lines lil. as shown, or the blank may be initially cutv to the form defined, between the top and bottom edges of the blank and the lines 19. In any event, the blank when folded along the median line is stitched after the manner shown in Fig. 7 of the drawings. In this embodiment of my process, as in the embodiment first described, a line of stitching is formed upon the folded blank which will predetermine the contour of the back and sides of the finished article. In leggings made of cloth,

it is desirable that the over-lapping edges will come at the side of the leg as indicated in Fig. 12. Therefore. the blank as indicated in Fig. 7 is stitched in such manner that when the blank has been formed into the logging, the meeting edges will be straight, as indicated in Fig. 12. The blank, when it has taken the form illustrated in Fig. '7. is then preferably soaked in water or other liquid to make it more pliable, and when this has been done, the blank, which is now in tubular form, is positioned upon the forming apparatus. said forming apparatus comprising relativcl' movable scctions'l' and S. In this embodiment of the process, the forming member 8 is shaped to,correspond to the front portion of the finished legging, and the forming member 7 is shaped to correspond to the rear portion of the finished legging. the blank being positioned upon the forming apparatus so that the stitched portion comes at one side of said forming memher. The forming members are then caused to separate by mechanism which has been already described. such separation gradually distorting the tubular blank portion until it assumes the form shown in Fig. 9 of the drawings, and it will be noted that the form corresponds to the superficial configuration of the forming mcnibers without sulijccting ice will also be substantiallystraight as indicated in Fig. 12.

It willaccordingly be seen th'at' I have provided a; process well adapted to attain, among others, allthe objects and aimsof my invention which have been heretofore t'orth. By means of the described process, it is possible to effect a great saving in labor and niaterial, thus lessening the cost of production.
